Overdilation of a 6-mm Self-Expanding Stent with a 10-mm Balloon-Expandable Stent Graft Preserves Failing Meso-Rex Bypass

Pediatric extrahepatic portal vein occlusion (EHPVO) may result in adverse sequelae of portal hypertension, such as severe hypersplenism, thrombocytopenia, poor neurocognitive and somatic growth, and variceal bleeding (1). The preferred treatment for selected patients is a meso-Rex bypass (MRB) creation, restoring physiological perfusion of the intrahepatic portal vein through a conduit from the superior mesenteric vein to the left portal vein (1). The MRB is associated with reduced portal hypertensive complications, improved coagulation, somatic growth, and cognition (2).
